This is a set of offset dies that I've used on 20Awg and 18Awg steel and 1/8in Aluminum. I used a 50ton break press and printed them in both Sariya Tech Sculpt Resin and PLA both worked well. The resin did seem to last a bit longer but would start to crack after a while. Great for a small run or just seeing if it's worth it before buying a metal version.
The models a reversible so print one will go in the top of the press and the other goes on the bottom.
